HI Dan, We have found the digital clock in Prism series of A/D/A's (The Dream A/D and D/A and the ADA-8) to be quite good. We are also using several Sonic Studio/Metric Halo A/D/A's and are in the process of comparing them against the Prisms. We have no experience with the Apogee units you mentioned.
